Be it known that I, Arz'rnosy W, Losenopon, a citizen of the United. States, residing at Detroit, county of YVayne, State of Michigan, have invented certain new and useidl Imprpvernents in Qllfilt-S for Cour "uting scalcs, and declare the following to I e a hill, clear, and exactdcscripticn' of the the art to which it pertains to make and use the same, reference being had to the accompaniying dmwings,' wliich form a part'cf this speeificatmn;

My iuventionrelates to an improvement in charts for computing scales, shown in the accompanying drawings and more particu larly pointed out in the following specifics. tion and claims.

(lliai ts as ordinarily constructed for computing scales are prorided with a limited number of price or total value computations Sow in order, to determine a value above the computations indicated upon the chart, it has been necessarv for the party employing the scale to worn out the answer by mental operation it hcing impractical to display upon the chart the great nui-nher of numerals required by a scale of larger capacity for-the reason that the numerals would necessarily he'so small and confused that it would be difficult to The object of this invention is to provide for displaying a certain series of numerals indicating the weight and money ralue in such manner that they may be easily read.

) A further object is to provide for an increased number of computations over those ordinarily employed in charts of this character.

A further object is to provide means whereby the computations may be displayed on a horizontal line .in counter-distinction to fan-shaped charts employingv ronceniric arcs subdivided to show the computations. While my improvement may employed in charts of this character it is well known that serious objections have been raised to the use chute-shaped cha'rts, -this form limiting the number of compoions and necessitating the use of. smaller siiuncrals.

Other advantages and iinprovmucrts will hereafter appear. 7 In the drawings accompanying 183$ 3;?

To the left of tin: plate A are a series of open ings A through which numerals placed on plate B indicating the weight, may be vicwed,thcre being upon the plate A, numeralsfrom one to ten-pounds, indicating the ordinary capacity of the chart. The figures displayed through the opei'iings provide for a chart of an increased capacity.

a are a series of radu'ations adjaccnt to the openings 98, in icnting ounces or other fractions of a pound. 4

-bar'G,-the graduations g indicating the .bar on of upward movement of the chart- B'to the extent of placing the pound mark 2 at the left of the chart back of the aperture where the numeral 1 now appears. If two weights should be removed the capacity of the scale would be increased to thirty pounds and the indication of the increased weight capacity would be indicated to the user 0? the scale by reason of the numeral 3 appearing back F in Figs. 6, 7 and 8 indicates in dotted the movable plate may be manually operated if desired. The shank of the handle. being acting with a spring f adapted to force it into engagement with the graduated rack necessary adjustment required to set the movable plate so as to display theproper group of numerals for any desired weight and value. In order to provide. for an intions beyond what wouldbe possible in the space provided between the apertures through which the numerals are displayed, the computations may be arranged in stepped groups, as indicated at H on the chart B,each group occupying a space' equivalent to the distance between the rows of'openings in the plate A..-

I indicates a stepped slotted opening in the plate B, and J is a lug or screw secured to the plate A adapted to work in the slotted way I ,the object being to secure a lateral movement of the movable plate B with re spect to plate A'by means of which one of the off-set groups of figures H or computa tions may bedisplayed in place of those di rectly in line with the openings in piate A, as shown in'the drawings.

Having indicated the several parts by ref; erence letters, the operation of the scale chart will be readily understood.

. The money value of the article weighed is readily determined through the indicator which the price per pound is'displayed, when taken in conjunction with the weight graduations and the money, value computation displayed through the series of openings in line with said weight gradua tions, as in the ordinary form of computing scale chart. This invention has the advantage over the usual form of chart in that the tal line and also that the computations are has been possible on scale charts as ordinarily constructed, the present arrangement of the figures being much more legible than heretofore.

Should it become necessary to determine the money value of a commodity of relativ ly greater weight than may be determined on charts of say the ordinary ten pound capacity,-the movable plate or chart may be actuatedso as to display a new group of weight numerals and value coniputations to correspond therewith without confusing the face'of the chart with an increased number of numerals.

In the modification shown in 6, is indicated a frame having apertures formed in the arc of a circle, through which to view the numerals placed upon the movable plate B located directly back of the frame. The plate B in this case, moves in a horizontal direction and may be manually actu-' ated by an operating handle l! provided with a pointer co-acting with a graduated member attached to the scale frame indicating the capa'city'of the scale in its adjusted relation. For instance in line with the top row of openings A are numerals indicating weights from one to ten pounds with graduatingmarks located between each of the several openings to denote fractions of a pound. 'lhrough the several rows of apertures A are displayed value computations to correspond With-the weight indications directly'above seen through the apertures A at the price per pound denotedon the swinging-indicator bar C in ,line with the several rows of apertures A. For example, an article weighing six pounds and selling at five cents per pound (as'shown on the indicator bar) will amount to a total value of thirty cents. of the article run over six poundsand less than seven, the total weight will be indicated by the graduating marks between the apertures A which must'be added to the six pounds to determine the total weight. The total value'is denoted by numerals dis-- played between the thirty and thirty-fivecent apertures-in a similar manner to the figures (i, 7, 8, and 9 indicated between'the five and ten cent values in the same row.

It will be understood that while'the drawings do-not showlgraduations and numbers between all the .apertures indicating-penny values, the chart will be provided with the.

same as shown at the left of the sheet by the four grad iating marks indicated at Z) beneath which are the numerals 6, 7, 8, and

9. If the plate B be moved one space to the left the weight numerals adjacent the openings A would he changed ten points, that is to say, there would appear in all of the o 'icnings, with the exception of the last one,

the numeral 1;. and in the last opening to the right would appear the numeral 2, changing the weight capacity of the scale from the ten capacity shown to twenty pound capacity, and showing in the opening where now appears $.05 the numerals indicating $.55, and as the weight ca pacity in line with the 55 cents shows eleven pounds, it would be understood-that eleven Should the weight pounds of material at live cents per )ound would amount to fifty live cents. "lieu titty-five cents is indiiuitcd beneath the weight. capacity ll there would be displayed in line with the weight indications i ll l l. H. etc. the price indication 50, (30, (i5 and 70, respectively, indicating that ten pounds at five cents a pound would amount to titty cents and that twelve pounds at five cents per pound would amount. to sixty cents, and so on. In reading the small numerals six, seven, eight, nine, indicated at b onplate A, between the apertures, just referred to, they are to be considered in connection with the. number displayed through" the aperture preceding 't'hemftor instance, if cents should appear Where 5 cents now appears, the unit numeral is dropped and We read 56--57-58-59--. Thus the money radii ations are indicated at b on the mom er A, denoting the value of'an article when the same weighs fractions of a pound. For example, we will assume that the article purchased is sold at; five cents per pound and it weighs a pound and a fraction, theindieater bar 0 would indicate whether at five cents per pound the purchase amt uted to Elli. seven. eight. or nine cents. or A ty-six, fifty-seven. iifiiyaright, or fifty-nine cents; and likew se the graduations indicated at u on zlic member A, would \lei'iotc the total win r an: tlr traction of the indicator bar 41 Ht e total eight gradua lions a". nhile i (Vl in but eight marks, may readily be divided on imaginary lines inn sixteen null 13 In the nn'ulitii'ntior "hown in Fiq. 8. the lived plate A it. provided with a series oi apertures fori'i ed on the arc of a circle. .PlYUlUtl to the plate A and direcly back of it is a tau-shaped chart B on which are placed numeral indicating the value and also a writs of lilllilt2\l3- spaced therefrom adap ed to be vi wed through openings in the lll'rllt? to indicate ht. when the i b", r 1 u (ll ml is set to w in an inreased vviagh: i'uoiiticzr ion the char? it pointer i graduated bar the capa ity p; ous-rly described that 'l provid roinatica n :u-eouipsnying tlr-ivvin types of scales.
